Product Details

The DFC 4000 HybriDynamic Brake Pad line is positioned as a value-focused brake pad family with a hybrid compound that simplifies pad selection while maintaining predictable braking characteristics. For drivers servicing a Mercedes-Benz CLA250 rear brake pad set, Mercedes-Benz GLA250 rear brake pads, or Mercedes-Benz GLB250 rear disc brake pads, this formulation is aimed at steady response, controlled dust output, and quieter operation in normal street driving.

This part number, 4000-2271-00, is a rear disc brake pad set with four pads per set. It does not include mounting hardware or a pad wear sensor, and it is prepared for a mechanical wear sensor where equipped. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Squealing or noisy rear brake operation
• Excess brake dust buildup on wheels
• Uneven or inconsistent pedal feel
• Worn rear pads requiring replacement
• Reduced braking response during routine driving
